Answer:
x= 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30=45
Combine like terms:
2x+3x-30 turns into 5x-30= 45
5x-30=45
+30 +30
5x = 75
x = 15
Answer:
x = 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30 =45
5x-30 =45
5x =45+30
5x =75
x =75/5
x =15
What is the slope-intercept equation for the line below?
A) y = 5/4x - 4
B) y = 4/5x - 4
C) y = -4/5x - 4
D) y = -5/4x - 4
Answer:
A) y = 5/4x - 4Step-by-step explanation:
Slope-intercept formula
y = mx + b, where m = slope, b = y-interceptSlope formula
m = (y2 - y1)/(x2 - x1)Given points (on the graph)
(0, -4) and (4, 1)Slope is:
m = (1 - (-4))/(4 - 0) = 5/4y-intercept is
-4 as per the first pointSo the line is:
y = 5/4x - 4Correct answer option is: A) y = 5/4x - 4

The sum of 2 times a number and 8 is 7
Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
Answer:
2x + 8 = 7
x = -1/2
Step-by-step explanation:
"a number" can be signified by a variable.
So 2 times a number would give you 2x
And 8 would mean to add 8.
Is 7 means the end result is 7.
So 2x + 8 = 7
x = -1/2

Answer: 70
90+20=110
180-110=70
I hope this is good enough:
Answer:
70
Step-by-step explanation:
Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180

Can someone put this into vertex form?
y=x2+24x-15
Answer:
The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159
Step-by-step explanation:
The vertex form of the quadratic equation y = ax² + bx + c is
y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = hLet us use the facts above to solve the question
∵ y = x² + 24x - 15
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = 24
∵ h is the x-coordinate of the vertex point
∵ h = [tex]\frac{-b}{2a}[/tex]
→ Substitute the values of a and b to find h
∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]
∴ h = -12
→ To find k substitute y by k and x by h
∵ y = k and x = h
∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15
∴ k = -159
∴ The coordinates of the vertex point are (-12, -159)
→ Substitute the values of a, h, and k in the vertex form above
∵ y = 1(x - -12)² + (-159)
→ Remember (-)(-) = (+) and (+)(-) = (-)
∴ y = (x + 12)² - 159
∴ The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Z is the circumcenter. What is VZ?
Answer:
VZ is 24
Step-by-step explanation:
when we talk of the circumcenter, we mean a point in the triangle that has a uniform distance from each of the vertices of the triangle
What we mean by the circumcenter is that the length between this point and any of the vertices is the same distance
ZU is a distance between the circumcenter and the vertice
What we want to calculate top is same.
So therefore, the two are equal and we have the length of what we want to
calculate as 24

(WILL GIVE BRAINLIEST TO RIGHT ANSWER) a container holding water is 3/4 full. after pouring out 8 ounces it is half full. How many ounces can it hold? x = # ounces container can hold
Answer:
If x is the number of ounces the container can hold then x = 32
Step-by-step explanation:
The container can hold 32 ounces because if it was 3/4 full and then you poured out 8 ounces then that means there was 2/4 remaining.

The ratio of Braydon's number of laps he ran to the time he ran is 6:2. The ratio of Monique's number of laps she ran to the time she ran is 104. Explain why these ratios are not in a proportional relationship.
Answer:
They are not in a proportional relationship because Monique's number and time isnt a proportion. Instead it is a whole number. Like Braydon's his is 6:2 that is the correct way to write it.
Step-by-step explanation:
The ratio is not proportion.
What is ratio and proportion?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given:
The ratio of Braydon's number of laps he ran to the time he ran is 6:2.
The ratio of Monique's number of laps she ran to the time she ran is 10:4.
The simplest for Braydon is = 6/2 = 3/1
and, the simplest form for Monique = 10/4 = 5/2
As, 3/1 ≠ 5/2
So, the ratio is not proportion.

Y=2/3x+2-2x+3y=6
Answer:
answer for y=2/3x+2: y=2/3x+2
answer for -2x+3y=6: x=3/2y-3
pls give brainliest
Answer:
There are infinitely many solutions.
Step-by-step explanation:
There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.
Showing that both equations are equal: y=2/3x+2 -2x+3y=6
y=2/3x+2 Multiply by 3 on both sides
3y=2x+6 Rearrange (-2x on both sides)
3y-2x=6 More rearrangement
-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.

A bus travels at a speed of 40 miles per hour and reaches Hogville in 40 minutes. If a cab takes 35 minutes to reach the same spot, determine the speed at which it traveled.
Answer:
45.7miles per hour
Step-by-step explanation:
40mins = 2/3 hour
the bus travelled (2/3 x 40) miles = 80/3 miles
the cab took 35 mins (which is 7/12 hour) so it's speed is (80/3)/(7/12) miles/hour = 45.714 miles/hour (5 s.f.)
